WRINGER.

Application mea september 3o, 1925. serial No. 59,491,

The object of my invention is to' provide a wringer for washing machines of simple,

durable and inexpensive construction.

More specifically it is the object of my in.'- b vention to provide a washing machine wringer which may be constructed Yentirely ot' metal and employing improved means whereby the tension between the wringer rolls may be quickly released.

A further object is to provide improved means for varying the tension of the rollers, and in connection therewith'provide means whereby the position of the tension applying mechanism may be adjusted so the roll.- ers may be adapted to operate on goods of considerable thickness, such as bed `covers and the like.

A further bbject is to provide means whereby the material may be `more readily fed tothe rollers.

A further object is to provide an improved. drain board which may be locked in a number of operating positions relative to the main frame.

My invention consists in the construction. arrangement and combination of the various parts of the device whereby the `obiects con- I templated are attainedyas hereinafter more fully set forth` 4pointed out in my claim's,

and illustrated in the accompanying drawings, in which: v

provided with two pairs of `upwardly extending guide bars 12, one pair being mounted atthe outer end `of said frame member-11,

while the vother pair is'mounted near the Figure 3 is an enlarged detail view showgear casing` Each oithe members 12 has its inner facef provided with a vertical groove 13, said grooves being designed to slidably receive the roller bearing casings 14. These bearing members are of the ordinary construction. The bearing members 14 are provided with a shaft 15 whichl carries the wringer roll 16. One end of the shaft 15 is provided with a coupling member 17 which is rotated from a gearing mechanism within the housing 10. yThe upper ones of the bear! ings 14 are provided with a shaft 18 having a roller 19. The upper bearings 14 and the said roller 19 are adapted to move freely in a wertical plane toward and from the roller 6.

Slidably mounted on the upper ends of each pair of guides 12 is a saddle 20 which rests on the'top face of the lupper bearing members 14, asclearly shown in Figure 5. Mounted between the bearing members 14 and the/end of the rollers 16 and 19 are vertically arranged shield plates 21, each of said plates being provided with a vertical slot 22 designed to receive the shafts 15 and 18. The lower end of the plate 21 is secured to the sides of the lower ends of the members 12 b v means of rivets or bolts 23. Each end of the saddle is designed to receive a vertically arranged rod 24, the upper end of `each of said rods being provided with an enlarged 'L portion 25 and screw threaded.l

Said screw threaded portions arey mounted in a frame member 26 which extends longitudinally above the top of the roller 19 and is provided at each end with a downwardly extending casing or hood 27. The side embers of the hoods 27 are designed to engage the edges of the shield plates 21.

The top of the frame member 26 is provided with openings 28 which are designed to slidably receive the upper ends of the shield plates 21. The sides of the hoods 27 are designed to engage the edges of said shield plates and thereby provide means whereby said plates will form guide members p f or the frame member 26, so the said frame M v improved wringer comprises agear 'housing 10 having a horizontally arranged frame member 11. The frame member 11 is member'v is free to movevertically.

To cause the said member 2,6 to retain a parallel position relative to the rollers 16- while being moved vertically. I have provided downwardly extending tlanges 29 from the member 26 designed to engage the inner faces ofthe shields 21. Each of the rods 24 is provided with a spring 30 which provides means whereby yieldable pressure may be applied between the member 26 and the saddle 20, and in turn impart a yieldable pressure between the rollers 16 and 19.

For locking the frame member 26 against upward movement and at the same time providing means whereby the pressure between the rollers 16 and 19 may bc instantly released, I have pivotally mounted to the central portion of the upper surface ot' the member 26 a hand lever 31. The central portion of said lever 31 is pivotally connected to oppositely arranged slide bars 32 which are mounted on the upper surface of the member 26 by means of pins or rivets 33 which Operate in slots 34. The outer end of each of the bars 32 is provided with a beveled portion 35 designed toI engage the under surface of a cross bar 36 across the upper end of the slot 22 of the shield 21. The parts are so arranged that when the members 32 are in alinement with each other and extend longitudinally with the member 26, the beveled edges 35 will rest beneath the lower edgesof the bars 36, and thereby provide means for locking the said bar 26 against upward movement with the springs 24 under tension.

It will further be seen that if the handle 31 is rotated, the beveled ends 35 will be moved inwardly from beneath the bar 36 which will permit the bars 36 to be elevated and the tension between the rollers 16 and 19 instantly released. The tension between the roller 19 and the bar 26 may be varied by rotating the members 25.

Sometimes it is desirable to support the rollers 16 and 19 apart a slight distance so that thick material, such as bed covers, may be fed between the rollers without injury to the springs 24. This I have accomplished by providing a slot 37 in the upper end of each of the shield plates 21, said slots being designed to receive the beveled ends 35 of the bars 32, which will cause the bar 26 to be supported at a osition considerably above its normal worlging position, and thereby permit a considerable space between the rollers 16and 19.

By this construction, it will be seen that .the wringer may be easily and quickly assembled or taken apart for repairs, 1f so desired, -by simply releasing the latch members 32 and then-lifting the arm 26 from the plates 21, the saddle 20 and the springs 24 being retained in position relative to the arm 26 by means of nuts 38 on the lower ends of the said rods 24. The saddle 20 is lifted from the guides 12 at the same time the bar 26 is'removed. It will be seen that the rollers with their bearings may be easily removed.

Beneath the roller- 16 I have provided a drain board 39 which is pivotally connected to the inner faces of the plates 21 by means of rivets 40, so that the angle of said drain board may be tilted to either one of two positions for draining water in opposite directions. For retaining the drain board in either of its tilted positions, I have provided hook members 41 pivotally connected to the opposite edges of the lower end of one of the members 21 by means of one of the rivets 23, as clearly shown in Figure 1, said hook members being designed to engage the upper edge ot' the end plates 42 of the drain board. Said hooks limit the upward movement while the downward movement is limited by the bottom of the drain board, resting on one edge of the traine member 11, as clearly shown in Figure 7.

Mounted adjacent to each side of the roller 16 I have provided a feed plate 43 having at each end an upwardly extending end member 44, the upper end of each of the members 44 being pivotally connected to the plates 21 by means of rivets 45. The plates 43 are inclined downwardly and outwardly. The inner edges of the plates 43 are spaced apart from the roller 16 a slivht distance and supported in this position by means of pins or rivets 46, which extend outwardly and rest against the outer edge of the plates 21. By this arrangement it will be seen that the feed plates 43 are free to swing out wardly from the roller 16 a considerable distance, so that. in case the roller should become entangled or wound with material no injury will be caused to said feed plates. The feed plates are illustrated in their outer limit of movement by dotted lines in Figure 7 ,A the plates swinging back into position by gravity.

Thus it will be seen I have provided a wringer of simple, durable and lnexpensive construction formed in a number of units, said units being easily and quickly assembled, and which may be easily and quickly taken apart for repairs.

It will further be seen that I have provided means whereby the tension between the rollers may be instantly released, and means whereb the upper roller may be adjusted a consi erable distance from the lower roller to permit the feeding of heavy material.

It will further be seen that I have pr0- vided an improved shield whereby the clothing being operated upon will beheld out of engagement with the bearing members of the rollers.
